> <strong>Traffic</strong> control system for<br />
Thur<strong>in</strong>gia: coord<strong>in</strong>ated traffic<br />
control with six <strong>in</strong>tegrated tunnels<br />
The supervisory traffic control system for Federal<br />
Motorway A71’s Thur<strong>in</strong>gian Forest Kammquerung<br />
section was created by Heusch/Boesefeldt <strong>GmbH</strong>,<br />
under subcontract to QSG Verkehrstechnik <strong>GmbH</strong>,<br />
as the first system <strong>in</strong> Thur<strong>in</strong>gia. The Eichelberg<br />
A71 Tunnel and Jena A4 noise protection system<br />
were <strong>in</strong>tegrated as an <strong>in</strong>terim step. A subsequent<br />
extensions resulted <strong>in</strong> the establishment of a “supervisory<br />
traffic control system”.<br />
The traffic control system is a server system compris<strong>in</strong>g<br />
two redundant units. Each unit consists of<br />
a data base processor and an application and user<br />
server. The systems work <strong>in</strong> “hot standby” mode<br />
this way.<br />
The traffic control system manages the traffic<br />
tak<strong>in</strong>g <strong>in</strong>to account <strong>in</strong>formation from the six <strong>in</strong>tegrated<br />
tunnels’ operations equipment. For this<br />
purpose, the traffic control system is connected to<br />
the tunnel computers of the six <strong>in</strong>dividual tunnels<br />
and the supervisory control computer. The servers<br />
receive aggregated <strong>in</strong>formation from the traffic<br />
control system.<br />
<strong>Traffic</strong> data is collected <strong>in</strong> 15 seconds <strong>in</strong>tervals via<br />
the attached sensors.<br />
Disasters across multiple tunnels are dealt with<br />
<strong>in</strong> a coord<strong>in</strong>ated way supported by appropriate<br />
rerout<strong>in</strong>g measures over subord<strong>in</strong>ate nets. The<br />
rerout<strong>in</strong>g alarm <strong>in</strong>dication occurs via the rerout<strong>in</strong>g<br />
system’s automatic circuitry.
